Could you send v2 with the following changes ?


[1] Could you rename *.header_test.c to *.hdrtest.c ?
    (I just thought .header_test.c was a bit too long.)

[2] %.hdrtest.c should not depend on the header

This will avoid unnecessary regeneration of *.hdrtest.c

quiet_cmd_header_test = HDRTEST $@
      cmd_header_test = echo "\#include \"$*.h\"" > $@

$(obj)/%.hdrtest.c:
        $(call cmd,header_test)

[3] Please add '*.hdrtest.c' to  .gitignore, Documentation/dontdiff

[4] Please add '*.hdrtest.c' to 'make clean' (around line 1640 of top Makefile)
